Personally I don’t do it that way because a 4x4 plastic flood tray is like $200, and something like a Auto Pot system leaves less room for error as far as setup and monitoring/maintenance are involved. Along with the reasons stated by @Aqua Man.
I agree with that not very dry but let it dry around 30% and the fertirrigate til 60% or 70% once ir twice a day that cycle. Less water and im in the benchmark gpw with that system.
For discussion sake can you share your reasons for this? Why does it need to dry?
Yeah grow wise I'm about to play with promix HP in 7 gal airpots so I'm curious about the differences. It claims 30% perlite but it might be worth mixing in more.
How big of plants are you growing?
I have followed your method in the past, for the same reasons, but the last grow I changed to regular feeds and have seen a big difference. But I also bottom feed (certain grows like SOG) once into flower through auto feed and air the pots with holes to encourage air pruning. But I always flush through before I switch just in case.
I think the same but Also i have to Say that if u have seen the roots of a pure hydro... The are submerged And the roots grow the same...So say if I let my early veg stay saturated they grow great, but the roots don't as much, I was told to think of it like this,
If you got brought food and drink to the couch, you'd never walk to the fridge, you'd still get fat, but your weak ass legs wouldn't be as strong as the man who goes looking for it,.
Now I've no science to back any of this up. It's all just what I've picked up here and there
When you say a pure hydro system what do you mean? DTW, E&F, RDWC?
RDWC, roots fully submerged and You see a very Big root system, maybe with coco 100% of humidity happens the same?
Well, actually on 1st week of bloom with the same 50cuttings as the previous grow where i use coco slab with dry cycles.
When I'm hand watering yes run off every feed,. But I'm still only feeding just after lights on, so last run in 3 gallon pots I was watering daily with about 10% run off. But with my sog they're on aQuavalve so it floods to 20ml then drains while they feed. Then once it's empty it floods again, but I have perlite layer on bottom of pots do roots aren't sat in feed. So these do wet/dry by design. But until flower those same cuts in 1 gallon pots were hand fed with run off every feed.
I'm in my first grow ever. 70-30% coco perlite mix in 2.9gal fabric pot. Watering twice a day, using 2lt of water everyday. I felt like wasting/using a lot of nutrients, but a few times I had not watered in the morning and next time I had to use almost 2lt of water to get run-off. So I thought I would be using the same amount anyway. It just can make you feel overwhelmed sometimes, watering twice a day, especially with multiple plants. It was recommended watering at least three times a day for my pot size but it's too much for me with hand. Don't you need to get run-off in soil also? So when you water soil every 3-4 days, don't you use a lot of water? I thought maybe the amount of nutrients wouldn't be that different? Like I said this is my first grow ever and it's in coco so I have zero experience with soil. I'm happy with it mostly, it's 53 days from sprout.
Nope added none. The vermiculite i think added 0.1-0.2 ph increase. It will midly raise PH in my limited experience.
Most dont need it anymore. I use canna coco and it comes rinsed and prebuffered and certified pest free.
